no they wont. they are inframe drag pipes, especially the CPI's. im not really sure what rockets are
The Rockets are also in frame Drag pipes, more top end pipes that actually pull about 500rpms higher then CPI's ive run both, and find the cpi to be better, another great banshee pipe is the SHear in frames, great all around pipe, Eddie sanders is selling them now for like 509 plated which is a killer deal!
